T0 at whom, it may concern:

Be it known that I, ALBERT S. MARTEN, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Electric-Light Shades or Hoods; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to numerals of reference marked thereon, which form a part of this specification.

This invention relates to shades or hoods for incandescent electric lights, the objects of the invention being to enable the upper and lower parts of the shade or hood to be removably and yet securely fastened together, to obtain simplicity and cheapness of construction, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved shade or hood for electric lights and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the several figures, Figure 1 is a transverse central section of a portion of a shade having my improvements applied thereto. Fig. 2 is areverse plan of the shade or hood, and Fig. 3 is I a detail sectional view taken on line y, Fig. 2.

Heretofore in electric-light hoods the lower members for deflecting the rays of light from the lamp outwardly and downwardly have usually, ifnot invariably, been supported near the centers by extensions of the tubular connections through which the electrical conductors pass to the electric lamps. This construction materially interferes with the operation of removing the said lower members from the upper members when the parts are in operative connection. Myimprovement facilitates the removal of the lower members without interference with the other parts.

In said drawings, Zindicates the upperportion of the shade or hood, comprising a circular dished piece of sheet metal provided at its lower edge with a downwardly-turned margin 3. The lower member 4 of the hood or shade is also formed out of sheet metal and oppositely dished with respect to the upper member, being rovided at its edge with a bead 5, preferab y formed by rolling or turning the edge of the sheet metal over a wire 6, as is common in metal-working.

It will be understood that the said lower section or member 4 sets into the upper section or member 2, the peripheral bead 5 of the former fitting nicely within the depending flange 3 of the latter, as shown in Figs. 1 and 3 more particularly. To hold the said mem bers in this normal relation, I provide the said flange 3 of the upper section or member at two or more points with fixed lugs or pintles 7, projecting inwardly and adapted to support the edge of the lower section or mem ber 4. At a third point I provide said flange with a boss 8, either riveted or otherwise suitably secured thereto and providing a threaded socket for a screw 9. Said screw is adapted to project from the inner side of the flange 3 of the upper member, as do the lugs or pintles 7 described, and to serve in conjunction therewith for supporting the edge of the lower section or member 4. The outer end of the said screw is provided with a finger-piece 10 for turning, and between the said fingerpiece and the outer side of the flange 3 or its boss 8 is arranged a spiral spring 11 to prevent inadvertent movement of the screw, whereby it might become loosened from proper position.

Upon examination of Fig. 1 it will be noted that the lower member is centrally open, as at 13, the sheet metal at the margin of the opening being upturned to reinforce or strengthen the same, and thus prevent indentation or injury due to the passage therethrough of metallic parts when withdrawing or applying the lower member from or to the upper member. This central opening in the lower member is larger than the opening in the upper member to permit the free passage of the lamp therethrough.

By the construction thus described it will be seen that to separate the two parts of the shade or hood it is necessary only to turn the screw 9 out far enough to clear the edge or bead 5 of the lower section 4 of the shade,

when the two members or sections can readily be separated. At the same time when ICC they are fastened together they are held so securely as to prevent any possibility of escape or separation.

Having thus described the invention, what I claim as new is 1. The improved hood for an electric lamp comprising an upper, dished, sheet -metal member having a downwardly-flanged peripheral edge, a lower and oppositely-dished member separable from within the upper member and adapted to fit at its edges within the downward flange at said periphery, and lugs or pintles projecting inward, from the flange of the upper member, underneath the edge of said lower section, one of said pintles being movable outward from beneath the lower hood member to permit said lower hood member to drop from within said flange, substantially as set forth.
